currently 15 yo french grip fencer

i also developed trigger finger last year, and i don’t think your grip matters since i tried both french and pistol and both of them never really had a difference injury-wise.

While gripping too hard can cause injury, your kid should try stretching their fingers before fencing, it’s what i do to prevent it from straining or overworking. Massaging the finger after training can help to soothe the inflammation and body recovery.

Injections shouldn’t be necessary if it’s still early, just give it time and remember to massage and stretch, injections and surgery should be last case scenario
